Very possible. How are your distributor cap and spark plug wires?

So, is it possible my 1992 engine doesnt like the 0.040 gap?
Would it cause mis-fires? run crappy? or just lose HP?

I've had two Gen I's and they did not like anything over 0.038. But that's
the old oil coils for you. Right now I run NGKs at about 0.038 in my '95
Sport. 1996 and older magnums call for 0.035, 1997 and up magnums call for
0.040. I put a set of NGK's in my buddies 98 Laramie back in March. Gapped
tham right at 0.040. Not a gripe yet, and this guy isn't very hep on cars,
he's a tile setter. I have run AP3923 or 4's at 0.040 in mine. No
difference in performance or mileage except maybe a little better speed
going up a 7% or a long 3 or so % grade. Biff
